I would find a codeacademy style learning experience, but for advanced topics, very intriguing. I use python (django, scikit learn, and pandas) on a regular basis, and would definitely pay for a service that could interactively help me explore more advanced topics. As I further my understanding of python/cs/web development, I spend a lot of time googling and reading through irrelevant stack-overflow/blog posts until I finally find a post that explains the topic/feature I'm trying to understand. It would certainly improve my productivity if there was a place where I could concisely explore advanced topics - maybe a hybrid between docs (not in depth enough) and tutorials (many spend too much time on basics).

Well, do you mean a paid course, or free course like codecademy? As for the question, indeed, i find it very intresting.

Paid. Since I'd put a generous amount of effort into it. Since this is advanced level that would mean video demo with voice overlaid + slides and code practice. I'm thinking about premium version where you can submit your solutions and get some guidelines.

Yes, depending on price

To tell the truth - it would cost a bit. Anywhere from 50bucks for the very basic set of materials up to 200-300 for the premium package. Though that would be a one time payment.
